OTTO F. SEIBOLD, OF BROOKLYN, NEW YORK.

GUN-WAO.

SPECIFICATION forming part of Letters Patent No. 271,527, dated January 30, 1883.

Application filed August 7, 1882. (No model.)

Teelt 'whom 'it may concern Be it known that 1, OTTO F. SE1BoLD,a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New ,central portion of the metallic disk, and upon the discharge of the gun the wad and the starshaped disk are driven out without danger of injuring the barrel of the gun or of disturbing the correctness of the aim.

In the accompanying drawings, Figure 1 represents a sectional perspective view of my cartridge, showing the convex star-shaped disk before its central portion is depressed. Fig. 2 is a sectional side view of the same after the central portion of the star-shaped disk has been depressed and the cartridge is ready for use. Fig. 3 is a transverse section in the plane nv m, showing theform of my star-shaped disk when used in combination with a cartridge having a paper shell. Fig. 4 is a similar section, showing the form of the starshaped disk when used in combination with a cartridge having a metallic shell.

Similar letters indicate corresponding parts.

In the drawings, the letterA designates my star-shaped disk, which may be made ot tinned sheet-iron, sheet-brass, or other material suitable for the purpose. In the example shown in the drawings this disk is provided with six points; but I do not wish to confine myself to this number of points. It is essential, however, that the points shall be at uniform distances apart throughout the entire circumferr ence of the disk, and that they shall be of such a length that each point can readily. be bent in either direction without using any undue force. After the disks have been cut out they are exposed to the action of suitable dies for the purpose of rendering them hollow or convex, as shown in Fig. 1, and after they have been brought into this shape their outside diameter is exactly equal to the inside diameter of the cartridge-shells into which the saine have to be introduced. After a cartridge has been charged in the usual manner one of my star-shaped disks is placed upon the wad a, the convex side of the disk being turned upward, (see Fig.1,) and then,bya suitable tool, the central portion of the disk is depressed so that it lies flat upon the surface of the wad, as shown in Fig. 2. By this operation the diameter of the star-shaped disk is slightly increased, and the points of said disks are brought to bear against the inner circumference of the shell with sufficient force to retain the wad a and the charge of the cartridge firmly in position. i

VWhen my star-shaped disks areintended to be used with paper shells, Innake their points sharp, (see Fig. 3,) so that when the central portions of the disks are depressed, as above stated, their points will be forced into the body of the shell; but if my disks are intended to be used with metallic shells their points are flat-edged, as shown in Fig. 4, and when the central portions of the disks are depressed these dat edges impinge against the inner eircumference of the shells with suliicient force to retain the charge in position.

It will be seen from this description that when. my star-shaped disk is secured in the shell, as above described, all its points are brought to bear against the inner circumference of the shell with a uniform pressure, so that the wad is retained at all points and the danger that the said wad will tip up at one place or at another is avoided. At the saine time, if the gun is discharged, my disk is released uniformly all round, for as soon as the central portion of the disk is forced upward by the explosion of the charge the points are drawn in and the danger of injuring the barrel or disturbing the correctness of the aim is avoided.

I am aware of the patent granted to George Smith November 30, 1875, No. 170,643, being the assignee ofthe entire right under this pat; ent. In this case metallic disks are shown which bear some resemblance to mine; but they are provided with a large number of very short points, and they are placed into the cartridge-shell with their points projecting upward. By the force of the explosion the diam- IOO sition. I disclaim the devices shown in these two patents.

What I claim as new, and desire to secure by Letters Patent, is-

The combinatiomwith a cartridge-shell and with the Wad a, of a star-shaped convex disk, A,

which, after having been placed upon the Wad, 15

is depressed in its center, substantially as and for the purpose described.
